SAFE-LOCK.

ESPECYLFICATIQN forming part of Letters Patent No. 323,158, dated July 28, 1885.

Application filed December 30, 1854. (No model.)

To all whom it may concern.-

Be itknown that I, ALBERT KIRKS, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Safe-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skillecl in the art to which it pertains to make and use the same.

My invention relates to improvements in safe-locks, but more especially to the mechanism that connects the internal bolt-shifting device by which the safe-dooris bolted or 1111- bolted with the lever or external devices for operating the bolts, having for its object such an arrangement of the connecting mechanism that these intermediatc or connecting parts are moved upward to make such connections, and areheld in such elevated position to render the boltshifting device operative from the outside by devices operated through the medium of the permutation'lock, and in the absence of such support from the permutationlock-as, for instance, if thelock were broken or removed by violence-thesaid intermediate connecting parts would descend by gravity and disconnect the parts; or, if the parts were already disconnected, the said intermediate devices would remain depressed and render the bolt-shifting mechanism inoperative from the outside.

A further object is to provide a stop for the bolt-shifting device to prevent the safe-door bolts from being drawn back or unlocked, except the said connecting mechanism be ele vated above the stop, by means of which, if the permutation-lock, that furnishes the only means of raising such connecting parts above the stop, be broken or removed by violence or otherwise, the safedoor bolts are held securely as against concussion or other violent means applied to the outside of the safe.

with these objects in view my invention consists in certain features of construction and in combination of parts hereinafter described,

and pointed out in the claims.

In the accompanying drawings, Figure l is a side view in elevation of a portion of the inside of the safe-door, illustrating my improvements, showing the safe-door bolted and the parts in position disconnected, rendering the bolt-shifting mechanism inoperative from the outside. Fig. 2 is the same view, but showing the parts in a connected position, with the bolts drawn back or unlocked by means of the outside lever. Figs. 3 and 4: are end views in elevation, the former showing the parts connected and the latter showing the parts disconnected. Fig. 5'is a side view in elevelation of a portionof the outside of the safe-door, showing the knob of the permutation-lock and the lever for moving the bolts. Fig. 6 is a view in perspective of a portion of the bar that connects the safe-door, bolts, and a slide, and pins or lugs connected therewith that form the saidintermediate or connecting mechanism. Fig. 7 is a transverse section on the line ofx 0c, Fig.6. Fig. Sis a side view in elevation of the notched disk connected with the outside lever for shifting the bolt, and shows also a stop that prevents the bolts from being withdrawn when the parts are disconnected. Fig. 9 is a view in perspective showing a modification in which a rock-arm is substituted for the slide D shown in Figs. 3, 4, 6, and 7.

A represents the door of the safe provided on the outside with the knob a of the permutation-lock and the lever or handle B. The spindle b,that forms the fulcrum for the lever, passes through the door, and is connected directly or indirectly, as the case may be, with the disk B,that is provided with the notch b. On the inside of the door are the bolts 0, of which there may be any desired number, and they are arranged to slide in the supports 0 andare connected by the shifting or carrying bar 0, by means of which the bolts are moved endwise in bolting or unbolting the door. The bar 0 does not connect directly with the disk B, and without some connecting device the turning of the lever B and disk B would not move the bolts 0 and carrying-bar C.

The intermediate or connecting mechanism may be as follows: A vertically-sliding block, D, is connected with the bar 0, preferably by a cap, E, atongue of which, e,extends through a corresponding slot in the block D,and is secured to the bar 0, as shown in Figs. 6 and 7. To the block D are attached the pins or lugs d and (2, usually extending in opposite directions, and might be formed of one continuous as shown more clearly in Figs. 4 and 6, the

pin (Z is below the disk B, and is approximately in the .same vertical plane with the axis of the spindle b,.and when elevated, as

shown in Fig. 3, will, if the disk B is in the right position, enter the notch b, in which latter position, by turning the disk (by means of the handle B) a lateral movement is given to the pin d, block D, bar 0, and the bolts 0. The elevated and depressed positions of the pin (1 are also shown in dotted lines, Fig. 8.

For elevating and depressing the block D and pin d in making the said connections between the bar 0 and the disk B, so that the bolts 0. may be moved from the outside by means of the lever B, I have provided the lever F, of the bell-crank variety, that is pivoted at F. The lateral arm of the lever is slotted longitudinally at f and embraces the pin (1. The upright arm of the lever is provided with the laterally-projecting pinf,that operates in the vertical slotg of the bolt G of the 'iermutation-lock G. When the bolt G is moved to the left-hand, (see Figs. 1 and 2,) the lateral arm ofthe lever F is raised, and by means of the connect-ions already shown the pin (Z is elevated and enters the notch 12, and when the bolt G is moved to the right hand the pin (Z is depressed and disconnected from the disk B.

A stop, H, is secured to the door in such position that when the bolts are moved for ward and the door consequently fastened the pin (Z when depressed will pass down in front of the stop H, in which position the pin (1, the bolts G, and connected parts cannot be moved back to unbolt the door, except the pin (2 be again elevated so as to pass over the stop, which can only be done by means of the permutation-lock aforesaid; also, when the bolts 0 are drawn back, the pin cl is above the stop H, (see dotted lines at the loft in Fig. 8,) so that the pin (2 cannot in this position be depressed, and the said lock cannot be operated or locked unless the pin d is moved forward, which movement forward of course bolts the door.

It will be seen, therefore, that by means of the connections between the bolt G and the pin 02, whereby positive vertical movements are transmitted from the former to the latter, the permutation-lock cannot be secured or locked except the safe-door be first bolted, without which arrangement the safe door might through inadvertence be left unfastened, although the operator had taken the precaution to secure the lock. As aforesaid, if the lock G were broken or forced from its fastenings, for instance, by an explosion of dynamite on the outside, the bolts would re main secured, ahd there would be no means of unlocking them from the outside, and no jarring or other violence from the outside would raise and hold the said intermediate connections while the bolts are being withdrawn; also, by reason of the stop H, the bolts cannot be jarred back or unbolted, and as the bolts 0 where they enter the holes in the wall or casing of the safe do not engage the said walls endwise, but, on the contrary, there is usually some little space between, an explosion of dynamite would only recoil 8c the walls and would have little effect in forcing back the bolts, especially when held, as aforesaid, by the stop H.

Various modifications may be had in the arrangement of parts without departing from the spirit of my invention. For instance, the sliding block D might be omitted, and an arm, D, pivoted to the bar 0 and supporting the pins (1 and d, might be substituted, and if by the arrangement of other parts these pins on were separated some distance, the one above the other, two such arms D might be used and connected by a rod.

What I claim is- 1. The combination, with a safe-door, bolts, and a handle having a notched disk thereon, of a lock, a lever connected with the bolt of said lock, and a pin forming a connection with the bolts and notched disk and directly connected with said lever, whereby it is posi- I00 tively moved up and down to engage with or be disengaged from the handle, substantially as set forth.

2. The combination, with a safe-door, sliding bolts, and ahandle provided with a notched I05 disk, of a permutation-lock, a lever connected with the bolt of said lock and provided with an elongated slot, and a pin passing through said slot and adapted to form a connection between the notched disk and sliding bolts.

3. In a safe-lock, the combination, with a door, sliding bolts, a handle, a notched disk, and the stop H, of a pin or lug and devices for moving said pin or lug into the notch in the disk, whereby a connection is formed be- I15 tween the handle and sliding bolts, substan tially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 24th day of December, 188i.
